A wheel for a racing bicycle including a rim with a rim body having a rim well and lateral rim flanks provided with rim flanges, the rim flanges showing bulges protruding inwardly, each defining an undercut at the pertaining rim flange. A tire with two circumferential tire beads is accommodated on the rim body between the rim flanges, the tire beads bearing against the inside of the rim flanges and entering the undercut at the bulges of the rim flanges. A tire retaining device is included which is disposed in the internal space between the tire and the rim well. The tire retaining device includes an insert member having a hollow space that extends between the tire beads and contains a radially outwardly peripheral wall and a radially inwardly peripheral wall, wherein at least the radially inwardly peripheral wall extends continuously across an inner axial width of the insert member.
